Description

Die Erfindung betrifft eine Vertikal-Drehmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a vertical lathe according to the preamble of claim 1.

Mittels derartiger Vertikal-Drehmaschinen werden vor allem groß dimensionierte Bauteile bearbeitet, beispielsweise Rotoren von Windkrafträdern oder dergleichen, die neben großen räumlichen Abmaßen sehr schwer sind.By means of such vertical lathes mainly large-sized components are processed, such as rotors of wind turbines or the like, which are very difficult in addition to large spatial dimensions.

Bei der Bearbeitung wird das aufgespannte Werkstück durch Verdrehung des Arbeitstisches in die jeweils gewünschte Position gebracht, in der dann das spanende Werkzeug in Eingriff kommt.When machining the clamped workpiece is brought by rotation of the work table in the desired position in which then the cutting tool is engaged.

Die Verdrehung erfolgt bislang über mindestens einen Motor mit einer Antriebswelle, die über ein Zahnradgetriebe mit dem Arbeitstisch in Eingriff steht.The rotation is done so far about at least one motor with a drive shaft which is connected via a gear transmission with the work table in engagement.

Aufgrund der zu bewegenden Massen, die sich aus dem Gewicht des Bauteiles und aus dem des Arbeitstisches ergeben, werden vor allem die Getriebeteile, wie die genannten Zahnräder, in sehr hohem Maße mechanisch beansprucht, insbesondere bei einer Beschleunigung und Abbremsung, was sich nachteilig auf die Standzeit der gesamten Vertikal-Drehmaschine auswirkt.Due to the masses to be moved, resulting from the weight of the component and from the work table, especially the gear parts, such as the said gears, mechanically stressed to a very high degree, especially during acceleration and deceleration, which is disadvantageous to the Life of the entire vertical lathe effects.

Naturgemäß ist dies mit erheblichen Kosten verbunden, die sich zum einen aus einer notwendigen Reparatur der verschlissenen Teile ergibt und zum anderen aus den Stillstandszeiten der Maschine.Of course, this is associated with considerable costs, resulting on the one hand from a necessary repair of the worn parts and on the other hand from the downtime of the machine.

Aber auch die Bearbeitungszeiten, zu denen die Beschleunigungs- und Abbremszeiten zählen, sind durch den verwendeten Antrieb nicht weiter zu verkürzen, so dass die bekannte Vertikal-Drehmaschine hinsichtlich der gestellten Forderungen nach einem wirtschaftlich optimierten Betrieb nicht gerecht wird.But also the processing times, which include the acceleration and deceleration times are not to be shortened by the drive used, so that the known vertical lathe with respect to the demands made for an economically optimized operation is not fair.

Darüber hinaus gestaltet sich eine erforderliche Reparatur insbesondere der Antriebseinheit schwierig, da ein Zugang zu den entsprechenden Bauteilen nur mit einem großen Demontageaufwand möglich ist.In addition, a required repair in particular the drive unit is difficult because access to the corresponding components is possible only with a large disassembly effort.

Eine gattungsgemäße Vertikal-Drehmaschine ist aus der DE 20 2007 017353 U1 bekannt. Der darin geoffenbarte Wanderfeldmotor ist in einer ringzylindrischen Ausnehmung des Untertisches angeordnet, wobei der Rotor und der Stator hochkant positioniert sind, unter Bildung eines vertikal verlaufenden Luftspalts.A generic vertical lathe is from the DE 20 2007 017353 U1 known. The traveling wave motor disclosed therein is arranged in a ring-cylindrical recess of the undertable, with the rotor and the stator positioned upright, forming a vertical air gap.

Der Erfindung liegt die Aufgabe zugrunde, eine Vertikal-Drehmaschine der gattungsgemäßen Art so weiterzuentwickeln, dass sie konstruktiv einfacher aufgebaut ist und kostengünstiger herstell- und betreibbar ist.The invention has for its object to further develop a vertical lathe of the generic type so that it is structurally simpler and cheaper to manufacture and operable.

Diese Aufgabe wird durch eine Vertikal-Drehmaschine mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a vertical lathe with the features of claim 1.

Durch diese konstruktive Ausgestaltung einer Vertikal-Drehmaschine ist eine besonders effiziente Bearbeitung insbesondere großer Bauteile möglich, da der Einsatz eines Wanderfeldmotors erhebliche Vorteile mit sich bringt.This structural design of a vertical lathe enables a particularly efficient machining, in particular of large components, since the use of a traveling-field motor brings considerable advantages.

Zunächst einmal kann auf ein Getriebe verzichtet werden, da die einen Stator bildenden Primärsegmente in unmittelbarer Korrespondenz zu den einen Läufer bildenden Sekundär-Segmenten stehen.First of all, a transmission can be dispensed with, since the primary segments forming a stator are in direct correspondence with the secondary segments forming a rotor.

Der auch als Linearmotor bekannte Wanderfeldmotor wird im vorliegenden Fall zum rotierenden Antrieb des Arbeitstisches genutzt, der die Sekundär-Segmente aufnimmt.The traveling-field motor, which is also known as a linear motor, is used in the present case for the rotary drive of the work table, which receives the secondary segments.

Diese sind in einem Trägerring des Arbeitstisches fest positioniert und, ebenso wie die unmittelbar gegenüberliegenden Primär-Segmente, ringförmig angeordnet.These are firmly positioned in a support ring of the work table and, like the immediately opposite primary segments, arranged in a ring.

Durch den möglichen Verzicht auf ein Getriebe, insbesondere auf ein ZahnradGetriebe, ist die Stör- und Verschleißanfälligkeit insgesamt minimiert, so dass die sich daraus ergebenden, nicht unerheblichen Kosten vollständig entfallen.Due to the possible omission of a gear, especially on a gear transmission, the susceptibility to failure and wear is minimized overall, so that the resulting, not inconsiderable costs completely eliminated.

Die Beschleunigungs- und Bremszeiten sind prinzipbedingt bei einem Wanderfeldmotor sehr gering, mit der Folge einer Verkürzung der Bearbeitungszeit in einem durchaus bemerkenswerte Maße.The acceleration and braking times are inherently very low in a traveling-field motor, with the result of a shortening of the processing time in a quite remarkable extent.

Neben seiner einfachen Bauart zeichnet sich der Wanderfeldmotor durch seine Robustheit aus, die eine hohe Standzeit garantiert, so dass die Betriebskosten gegenüber einer Vertikal-Drehmaschine nach dem Stand der Technik erheblich gesenkt sind.In addition to its simple design, the traveling wave motor is characterized by its robustness, which guarantees a long service life, so that the operating costs compared to a vertical lathe according to the prior art are significantly reduced.

Für den Fall, dass eines der ortsfesten Primär-Segmente schadhaft sein sollte und ausgetauscht werden muss, ist nach einer vorteilhaften Weiterbildung der Erfindung vorgesehen, den Arbeitstisch mit einer Durchgriffsöffnung zu versehen, die mit einem abnehmbaren Deckel verschlossen ist und durch die ein Zugriff zum Austausch des entsprechenden Primärsegments möglich ist.In the event that one of the stationary primary segments should be defective and must be replaced, it is provided according to an advantageous development of the invention to provide the work table with a through-opening, which is closed with a removable cover and through which access to the exchange of the corresponding primary segment is possible.

Dabei ist die Durchgriffsöffnung in ihrer Grundfläche so dimensioniert, dass ein jeweiliges Primärsegment bequem demontier- und herausnehmbar ist.In this case, the passage opening in its base is dimensioned so that a respective primary segment can be easily disassembled and removed.

Die Positionierung des Arbeitstisches hin zu dem auszuwechselnden Primärsegment kann taktweise erfolgen, wobei für einen freien Durchgriff zu dem entsprechenden Primär-Segment zweckmäßigerweise eine entsprechende Anzahl Sekundär-Segmente, die am Arbeitstisch positioniert sind, herausgenommen werden können, so dass ein freier Zugriff auf das Primär-Segment gegeben ist.The positioning of the work table towards the primary segment to be exchanged can take place cyclically, for a free access to the corresponding primary segment expediently a corresponding number of secondary segments, which are positioned on the work table, can be taken out, so that a free access to the primary Segment is given.

Um eine weitgehend hermetische Abdichtung des den Wanderfeldmotor aufnehmenden Innenraumes sowohl des Untertisches wie auch des Arbeitstisches zu erreichen, ist im Außenrandbereich des Untertisches in Korrespondenz mit entsprechend konfigurierten Bauteilen des Arbeitstisches eine Dichtung geschaffen, die bevorzugt aus einem umlaufenden, mit einer Flüssigkeit gefüllten Dichtraum des Untertisches besteht, in die ein umlaufender Steg des Arbeitstisches eintaucht.In order to achieve a largely hermetic sealing of the moving field motor receiving the interior of both the undertable and the work table, in the outer edge region of the undertable in correspondence with appropriately configured components of the worktable a seal is created, preferably from a circumferential, filled with a liquid sealing space of the undertable exists, in which a circumferential bridge dips the work table.

Zweckmäßigerweise ist im Bodenbereich des Dichtraumes ein verschließbarer Ablauf vorgesehen, über den die Flüssigkeit im Bedarfsfall, wenn diese beispielsweise wegen Verschmutzung gewechselt werden soll, abgelassen werden kann.Conveniently, a closable drain is provided in the bottom region of the sealing space, through which the liquid can be drained if necessary, if this is to be changed, for example due to contamination.

Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous embodiments of the invention are characterized in the subclaims.

Die Durchgriffsöffnung 10 kann im Übrigen durch einen Deckel verschlossen werden, so dass der gebildete Innenraum, in dem der Wanderfeldmotor angeordnet ist, hermetisch gegenüber dem Arbeitsraum der Maschine verschlossen ist.Incidentally, the access opening 10 can be closed by a cover, so that the formed interior, in which the traveling-field motor is arranged, is hermetically sealed off from the working space of the machine.
